WASHINGTON — President Donald Trump's trade adviser Peter Navarro expressed regret Tuesday for having said there is "a special place in hell" for Canadian Prime Minister Justin Trudeau.

"Let me correct a mistake I made," Navarro said at a Wall Street Journal conference, according to video provided by the Journal's CFO Network. "In conveying that message I used language that was inappropriate."

Trump was furious after Trudeau had said at the end of a contentious economic summit in Quebec that he wouldn't let Canada be pushed around in trade relations with the United States.
